Reflectance, fluorescence yield, and photoelectron spectroscopy of CaF2 in the 10 to 100 eV range
— Reflectivity, fluorescence and photoelectron spectra from CaF2 single crystals hâve been measured using synchrotron radiation in the 10 to 100 eV range. The spectra contain features ascribed to excitons and to the band structure. Peaks due to conduction-band states derived from the 3d atomic levels are prominent in ail three
متن کاملVacuum-UV negative photoion spectroscopy of CF3Cl, CF3Br, and CF3I.
Using synchrotron radiation, negative ions are detected by mass spectrometry following vacuum-UV photoexcitation of trifluorochloromethane (CF(3)Cl), trifluorobromomethane (CF(3)Br), and trifluoroiodomethane (CF(3)I). The anions F(-), X(-), F(2)(-), FX(-), CF(-), CF(2)(-), and CF(3)(-) are observed from all three molecules, where X = Cl, Br, or I, and their ion yields recorded in the range of 8...
متن کاملAn improved fast - response vacuum - UV resonance fluorescence CO instrument
The fast-response resonance fluorescence instrument for the airborne measurement of carbon monoxide described by Gerbig et al. [1996] was modified by implementing an improved optical filter with more efficient optics and an optimized resonance lamp. Besides reductions in size and weight, the new instrument achieves a sensitivity 10 times higher, a lower background (65 ppb compared with 250 ppb)...
متن کاملConformation of L-tyrosine studied by fluorescence-detected UV-UV and IR-UV double-resonance spectroscopy.
The laser-induced fluorescence spectrum of jet-cooled L-tyrosine exhibits more than 20 vibronic bands in the 35450-35750 cm(-1) region. We attribute these bands to eight conformers by using results of UV-UV hole-burning spectroscopy. These isomers are classified into four groups; each group consists of two rotational isomers that have a similar side-chain conformation but different orientations...
